Application January s1, 193s, serial No. 61,7"15 This invention relates to a marine carrier4 and more particularly to a >ship of such construction that barges or other floating units may be floated n As _specifically illustrated on;Flg. .3, it ispro use barges of peculiar formationwhereby the space on this deck can be eiilciently utilized. These barges are in the form of an isosceles . Dosedto’ intoA place and carried economically over an extended trip. ` An object of the invention is to provide a ship streamlined in construction and, therefore, eco- ` nomical as a carrier in which barges or other iloating units may be loaded with other portions of the ship so constructed as to provide freight handling space. Another object of the invention is to _provide a trapezoid with'the sides of the barges forming 5 the bases of the trapezoid and the bow and stern of the barge forming the legs of the trapezoid. Barges oi' this peculiar construction and their general utility -are disclosed in my ap plication Serial No. 13,895, filed March 30, 1935. 10 It will be observed that the hatch trunks 9 are such as to form recesses in the side of the hori of separate water--tight units ail’ording as' it were zontal compartment formed by the upper deck I - .and barge deck 2 in which the barges will nicely a number of portable bulkheads. carrier for freight handling including a plurality lit. v 15 Another object of the invention is to~ provide a master wedging device lli` of the form shown carrier including a hull and a plurality -of port » in AFig. 3 may be placed adjacent the `gate 5. able units so shaped as to substantially cover an entire deck and so arranged that the units may 'I'he member i0 has screws I l by which the device be readily wedged and held securely in position. may be operated.

Fig. 1 is a side elevation of a ship embodying this invention; ' _ - Fig. 2 is a plan view showing the upper deck; Fig. 3 is a plan view showing an intermediate or barge carrying deck; ' Fig. 4 is a plan view showing a hold deck; Fig. 5 is a vertical cross-’section of the ship; and Fig. 6 is a side elevation of a ship showing a modification. The ship. as specifically illustrated in Fig. 1, in Ui cludes a hull with an upper deck l, a main or barge carrying deck 2, and a hold 3. 'I'he hull has a double bottom and sides to provide ballastl tanks L _ By pumps, >not shown, the ballast tanks may be filled 4and emptied to control the depth at which the ships rest in the water, thus permit and all of the barges will be wedged in place. `When it is desired to pass the barges, the wedging - device III maybe removed'or it may be merely raised above the top of the barges. It is to be understood that except as limited by the claims 25 vthe invention is not connned to the use of ñoating units of the shape mentioned or to the particular .f Awedging or bracing means, although much utility resides in their use, By the provision of the carrier as specifically 30 described, barges suitable for use _in a harbor or for use on inland lakes, rivers and canals may > be directly loaded o_n the ship while provisions are made for elsewhere carrying freight, thus economizing in the use of space and making the 35 carrier an efficient transportation device. A construction embodying these improvements contains an added element of safety. The barges are watertight lcompartments and comprise, in ting a ship to be submerged 'to a line below the » effect, movable bulkheads. Should, for example, 40 deck 2. A water-tight gate 5` is provided f by the ship’s hull be damaged sufliciently to sink a ship of ordinary arrangement, the buoyancy of which access to the barge deck 2 may'be had.

It is obvious, of course, that some of these upon their deck, until they reached the overhead "45 tanks 8 may and will be used for fuel oil for deck l, and then their buoyancy would assist in fresh water and for other purposes than liquid ñoating the hull.
